Tivoli Storage Manager Introduction

1)What is BACKUP?Backup is nothing
but taking a additional copy of data Objects to be used for recovery. Backup
data consist of several versions. Each version at different point in Time but
It follows the main Object version.

2)What is archive?

Archive is nothing but Taking additional
copy of file as a separate object in the storage repository to be retained for
specific period of time. But in archive it does not have any versions.

3)What are all
different types BACKUP APPLICATIONS available in current trend?

TSM stands for Tivoli Storage Manager; It
is a Enterprise level backup solution. It was released in July 29th 1993, earlier
it is Called as ADSM. When it was taken
by IBM It is called as ITSM. It is mainly used to
protect the data from hardware failures and other errors, and it is used in
Enterprise level.

In
tsm server we will register the
node and we will install b/a client
software in that System and we will specify server address, node name
, password access generate and few options
in dsm.opt of client
machine and we log into that particular
client and we will take the backup and
that data goes from the client to
server and in server first it checks
whether the node is registered or not
and once it is authenticated and server allows the client data in to storage
pool and when it reaches to certain
highmig value automatically

Migration starts and it moves to
secondary storage pool.

Note: while taking backup it starts the
two sessions one is used to send the meta data and second is used to send the
actual data.

11)What are TSM
Components? Explain it?

The components are:

Database: It is used to store
the complete Meta information of the clients, client data, server information
(Meta data:-The information about the data)

Recovery
log:
It is used to maintain a record of transactional changes in the database .It is
of two modes 1) Normal mode 2) roll forward mode

Storage
pool:
It is the place where the client data objects are stored

B/A
Client: It is client application software, in which system we want to take
the backup we will install in that.

Policy
management: It enables the administrator to determine a set of rules how TSM will
treat data. This is set of rules is composed of policy domains, policy sets,
management class and copy groups

Scheduler: It is an automated
action used to run the schedule at the specific period of time.
